Abstract: A printer valve assembly including a plurality of valves. Each of the valves is actuated between an open state which permits fluid flow though the valve and a closed state which prevents fluid flow though the valve. The plurality of valves includes a first feed valve, a first return valve, a waste valve and a purge valve. The first feed valve controls flow between a source of first print fluid and a feed line to a print head. The first return valve controls flow between a return line from a print head and a source of first print fluid. The waste valve controls flow between a return line from a print head to a waste receiver. The purge valve controls flow between a source of purge fluid and a feed line. The printer valve assembly further includes a valve control member which is mechanically connected to the valves to simultaneously control the state of the valves based on a position of the valve control member.

Abstract: In an example, a method comprises, for an autonomous vehicle: coarsely positioning a first signal beam emitter located on the vehicle in line with a first alignment target and coarsely positioning a second signal beam emitter located on the vehicle in line with a second alignment target, wherein the first and second alignment targets are each aligned with a predefined grid. The method may include emitting a first signal beam from the first signal beam emitter towards the first alignment target and emitting a second signal beam from the second signal beam emitter towards the second alignment target. The method may further include monitoring a first return signal beam from the first alignment target and adjusting at least one of a position and an orientation of the vehicle based at least in part on the first return signal beam and determining that alignment is complete based at least in part on the first return signal beam.

Abstract: In an example, an autonomous vehicle comprises first and second sensors, wherein each of the first and second sensors is to acquire first and second position measurements for the autonomous vehicle. The autonomous vehicle may comprise a processor to compare the first and second position measurements and when the first and second position measurements are in agreement, determine a position of the autonomous vehicle by selecting the first position measurement, and when the first and second position measurements are not in agreement, determine the position of the autonomous vehicle by filtering the first and second position measurements with a stochastic filter.
